Milky Way Shadows
Photo and caption by Alex Cherney
Far away from man-made lights the Port Campbell National Park (Victoria, Australia) is very dark on a moonless night. The stars in centre our Milky Way Galaxy are the most significant source of light which helped to create dark reflections on the water in the middle of the frame. To render the dark scene close to what I saw I took 7 consecutive 15-second exposures in under 2 minutes interval. The sky in the exposures was de-rotated to compensate for the rotation of Earth, then images were stacked together producing an image identical to a single exposure but with less digital noise.
